Uni-Span Formwork ELEC1

1 FormworkSince it was established in 1989, with a small manufacturing base in Qwa Qwa and a hire yard in Botswana, Uni-Spanhas grown to become one of the major players in the scaffolding and Formwork industry in South is today one of the biggest scaffolding suppliers in the country and has, in Investec Bank, a financial partner thatunderstands the scaffolding business and is committed to making capital available to increase capacity as demand and above its supply of Formwork and scaffolding to various contractors across diverse building sites, the companyis also involved in some of the country s key infrastructure and industrial development projects. Uni-Span is supplyingmain contractors and subcontractors providing insulation, cladding and painting services to the refineries, mines and powergeneration has its own design office and in-house engineering expertise and has the ability to design standard support, Formwork and access systems to the client s particular requirements.

2 The design team calculates specific quantities andloadings of scaffolding and Formwork for each contract using the latest CAD WALL SYSTEMThe Uni-Span system consists of all steel economy panels. These areavailable in a combination of sizes from 75mm to 600mm wide and900mm to 3000mm long. Special sizes can also be made to panels are joined by wedge sets which are inserted through slotsin the punched flat which forms the edge of the panels are aligned by either tube or channel walers which areclamped to the panels with B or C heavy duty concrete work, form soldiers are used. The panels arethen gangformed and crane panels are tied together to form parallel faces using tie versatile panel system can be used to construct: walls , columnsbeams, culverts, bridges and pile panel system consists of 6 basic elements: Steel economy panels,tubular or channel walers, wedge sets, tie systems, push-pull propsor plumbing brackets and access PANELE conomy panels are an advanced multi-purpose Formwork systembecause.
